Reverse Osmosis Systems

Reverse Osmosis systems or RO Units as they are commonly named, are used by many aquarists in the aim of providing the aquarium with the best water quality available. RO units convert tap water into purified water, thus removing nitrates, phosphates, heavy metals etc.

Reverse Osmosis is the process of forcing water molecules across a semi-permeable membrane. Only water molecules can pass through the membrane therefore straining out the impurities that are unwanted. Once connected to the mains water supply two types of water are discharged, firstly the pure RO water and secondly waste water. Store the RO water for use in water changes etc. and dispose of the waste water down the drain.

RO water is ideal for marine and freshwater aquariums and will aid in reducing algae and other water quality issues.
